step S606, receiving a control instruction sent by the first wearable device, and in response to the control instruction, controlling the display device to enter a rest mode, wherein in the rest mode, the target multimedia data is stopped from being continuously played.
In steps S602 to S606 in the above-described device control method, the process of the device control method is described from the perspective of the display device, when a child watches a video through the display device, distance calibration is adopted, and when the distance is smaller than a first threshold value, the child conveniently enters a child mode through interaction between a child watch and the display device, so that the time length for watching the video by the child is accurately controlled across devices. It should be noted that, in the embodiment of the present application, the first wearable device may be a child watch worn by a child.
In order to support the above functions, in some embodiments, the software architecture of the display device may be implemented by the architecture shown in fig. 7, and specifically, includes three parts, namely, an application layer, a Framework layer, and a kernel layer. In the application layer, the application layer comprises a connection module, a video application, a child mode application and other system applications, wherein the connection module is used for establishing a connection relationship between a display device and a first wearable device, the display device can be a large screen, a television and the like in the embodiment of the application, the first wearable device is a child watch worn by a child, the video application is used for providing software support for watching videos, the child mode application provides a function which can be used in a child mode in the current mode, and the other system applications provide functions when the child mode is connected with other hardware or systems; in the Framework layer, four parts of a bluetooth module, activity management, window management and notification management are included, the bluetooth module is used for providing wireless data transmission and data control, and the activity management is used for providing management of activity corresponding to an application program, such as management of the period, state and the like of the activity. The window manager is used for managing window programs, and can obtain the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like. The notification management enables the application program to display notification information in the status bar, can be used for conveying notification type messages, can automatically disappear after short-time stopping, does not need user interaction, and can pop up notifications when viewed in a child mode; the kernel layer is the layer between hardware and the software, in the kernel layer, including bluetooth drive, camera drive and on-off module three, the bluetooth drive is passed through the bluetooth by display device and is connected with first wearable equipment or other equipment, and the camera drive is used for detecting the distance between children's distance display device, and the on-off module is used for supporting the function that display device started or shut down.
Accordingly, as shown in fig. 8, the architecture of the child watch includes three parts, namely an application layer, a Framework layer and a kernel layer, in a software architecture diagram of the watch. The application layer comprises a connection module, a child timing application and a wearing detection part, wherein the connection module is used for establishing a connection relation between the child watch and the display device, the child timing application is used for timing the time of watching a video by a child, and the wearing detection is used for detecting whether the child wears the watch; the Framework layer comprises a Bluetooth module and a gravity sensing module, the Bluetooth module is used for providing wireless data transmission and data control, and the gravity sensing module is used for controlling the rotation of the child watch according to gravity, so that the child watch is convenient to watch and use; in the inner core layer, a Bluetooth driver is included, and the Bluetooth driver is connected with a display device or other devices through Bluetooth by the child watch. After the connection relationship between the display device and the child watch is established, the parent charges the child watch with the charge time through the mobile terminal logged in by the adult account (the mobile terminal of the parent and the child watch are also connected, for example, through bluetooth and other modes), for example, the parent can watch 5 hours per week, and can watch 1 hour every day, and the child watch obtains the time record after charging to the local through the mobile terminal or the cloud, and times the use time of the child through the child timing application.
In the related art, a mode of increasing an entrance and reducing the entrance depth is mostly adopted, a user needs to perform click operation or voice awakening for entering in 3 to 5 steps, the time consumption is about 8 to 15 seconds, only the control of single watching time and weekly watching time of a single device can be achieved in time control, and cross-device control cannot be performed.
In order to solve the above problem that cross-device management and control cannot be performed, in step S604 of the device control method, before the display device plays the target multimedia data, it may be further detected whether a designated electronic device exists around the display device, and it should be noted that, in this embodiment of the present application, the designated electronic device may be an adult watch worn by an adult, that is, the usage right is greater than the usage right of the first wearable device, where the usage right may be understood as a control right for the display device, and the meaning that the usage right of the designated electronic device is greater than the usage right of the first wearable device includes but is not limited to: the control function of the display device by the designated electronic device is more than that of the first wearable device, the designated electronic device can be used for setting or limiting the use permission of the first wearable device to the display device, and the designated electronic device comprises but is not limited to electronic devices such as a watch, a bracelet, a mobile phone and a Pad.
For example, when a specific electronic device is detected within a detection range of the display device, the display device sends an authorization request message to the specific electronic device, where the authorization request message is used to request the specific electronic device to enter a preset mode, where in the preset mode, the target multimedia data is allowed to be played; and receiving a response message corresponding to the authorization request message from the specified electronic equipment, and determining whether to send the first notification information according to the response message, so that the cross-equipment management and control of the first wearable equipment are realized.
In the above processing procedure, when the display device detects that an adult watch exists around the display device and the distance between the first wearable device and the display device is smaller than the first threshold, the display device sends authorization request information to the adult watch (i.e. the designated electronic device) within the detection range of the display device through step S612, and then displays the prompt information in the interactive interface of the adult watch, and provides a confirmation button, where the confirmation button includes a play permission button and a play rejection button, and may be specifically represented as being provided with a ": the button comprises two buttons of 'yes' and 'no', wherein if the button 'yes' is triggered, a response message for confirming that the playing is allowed is sent to the display device, if the button 'no' is triggered, a response message for refusing the playing is sent to the display device, specifically, the authorization request information can be 'child approaches, watching time is xx minutes left, and whether the child mode is entered or not', and it needs to be stated that the child mode is the preset mode mentioned above, and if the family member confirms that the child mode is entered through the adult watch, the display device is allowed to play the target multimedia data; and if the keeper selects to refuse to enter the child mode through the adult watch, refusing to play the target multimedia data.
As can be seen from the above, in a specific application, the response message corresponding to the authorization request message may be understood as a message confirming whether the display device enters the child mode.
It should be noted that, before the first distance (i.e., the relative distance between the display device and the first wearable device) is smaller than the first threshold, if the state of the display device is the screen-locking state, the child mode is denied or the multimedia data is not allowed to be played. The method specifically comprises the following steps: and maintaining the screen locking state.
Before the first distance (i.e. the relative distance between the display device and the first wearable device) is smaller than a first threshold, if the state of the display device is that multimedia data is being played, and if the duration of the state where the first distance is smaller than the first threshold is longer than a specified duration, determining a control strategy of the display device according to the type of the multimedia data being played, specifically: determining the type of multimedia data being played; stopping playing the multimedia data when the type of the multimedia data being played is a specified type, wherein the specified type includes but is not limited to: non-children programs, etc. In this scenario, if the response message is a response message confirming that the playing is allowed, the display device may stop playing the specified type of multimedia data and start playing the target multimedia data; if the response message is a response message rejecting the play, the display device may stop playing the specified type of multimedia data and not play the target multimedia data.
In order to further enhance the user experience, besides the confirmation button is shown to the user (here, the user is a parent or the like) at the side of the second wearable device (for example, the above-mentioned adult watch), a corresponding prompt message may also be shown in the interactive interface of the display device to prompt that the user of the first wearable device is waiting for confirmation, and the prompt message may be a similar prompt message such as "waiting for confirmation to enter the child mode".
In some embodiments of the application, the detection range of the display device may be determined by an effective communication distance of a near field communication method such as bluetooth, and when the specified electronic device is within the bluetooth detection range of the display device (that is, the distance between the second wearable device and the display device is not greater than the effective communication distance of the bluetooth communication module), it is determined that the specified electronic device is present near the display device.
In order to implement synchronization of the playing timing, as described above, the display device needs to send first notification information to the first wearable device, where the first notification information is used to notify the first wearable device to start timing the playing process of the target multimedia data, so that the timing process of the first wearable device and the playing time of the target multimedia data can be synchronized, for example, when the first wearable device starts timing, the display device plays the target multimedia data, and at this time, the first notification information may carry the playing start time of the target multimedia data, so that the first wearable device considers the playing start time in advance before timing, for example, the timing start time is advanced by a corresponding time length (for example, a time length between the timing start time and the playing start time). By adopting the scheme, the synchronization of the playing process of the display equipment and the timing process of the first wearable equipment can be realized, and the problem that the playing time of the first wearable equipment and the playing time of the display equipment are not synchronous due to the fact that the display equipment starts to play the target multimedia data and the first wearable equipment does not start timing is avoided. Before the display device plays the target multimedia data, under the condition that the designated electronic device is not detected in the detection range of the display device, first notification information is sent to the first wearable device, wherein the first notification information is used for notifying the first wearable device to start timing in the playing process of the target multimedia data, and the first notification information carries the playing starting time of the target multimedia data.
For example, if the display device does not find an adult watch in the detection range in a bluetooth manner or the like, that is, under the condition that no specific electronic device is found, if the current time is not in the rest period and the remaining viewable time of the first wearable device in which the child logs in is greater than 0, the display device automatically enters a preset mode, that is, automatically enters a child mode, and sends first notification information to the first wearable device, where the first notification information carries the play start time of the target multimedia data. By way of example, if the play start time in the first notification information is 8, and the current time is 8, the display device may play the target multimedia data at 8.
In step S604 of the above device control method, when the display device plays the target multimedia data, the method may further perform the following steps:
under the condition that the appointed electronic equipment is not detected in the detection range of the display equipment, the display equipment records the play starting time of the target multimedia data and starts timing at the play starting time; and sending second notification information to the first wearable device at a preset time period, wherein the second notification information is used for notifying the played duration of the target multimedia data. The second notification information is used for notifying the played time length of the target multimedia data of the first wearable device.
After the first wearable device receives the second notification information, the played time length of the target multimedia data played by the display device is compared with the played time length of the target multimedia data recorded by the first wearable device, if the played time lengths of the target multimedia data recorded by the display device and the target multimedia data recorded by the first wearable device are consistent, no processing is performed, namely any time length is taken as a reference; if the played time lengths of the target multimedia data recorded by the two parties are not consistent, the played time length of the target multimedia data in the second notification information sent by the display equipment is taken as the standard, and the first wearable equipment adjusts the played time length of the recorded target multimedia data and keeps consistent with the played time length of the target multimedia data recorded by the display equipment.
Besides sending the second notification information to the first wearable device, the display device can also send the second notification information to the designated electronic device in order to enable adults to know the time length of the multimedia data watched by the children in real time, and parents can timely know the played time length of the target multimedia data after the designated electronic device receives the second notification information. When the adult thinks that the children watch the video for a long time, a playing stop instruction can be sent to the display device through a specified electronic device (such as an adult watch) so as to control the display device to stop playing the target multimedia data.
It should be noted that the priority of the stop playing instruction is relatively high, for example, even if the played time of the target multimedia data is less than the specified time, that is, the playable time corresponding to the first wearable device or the child account logged in by the first wearable device is less than the viewing time allowed by the adult, after receiving the stop playing instruction, the display device may still stop playing the target multimedia data.
Under the condition that the display device does not detect the designated electronic device in the detection range in the manner of bluetooth or the like, the display device records the play start time of the target multimedia data, sends first notification information to the first wearable device, notifies the play start time of the target multimedia data of the first wearable device, and sends second notification information to the first wearable device in a preset time period, wherein the preset time period can be set to 1 minute, but is not limited thereto, and specific values can be determined according to actual conditions.
In order to prevent the misjudgment of the display device, for example, a child only stops or passes before the display device for a short time, if the corresponding multimedia data is triggered to be played, a bad experience may be brought to the user, and therefore, in some embodiments of the present application, before the target multimedia data is played by the display device, the misjudgment may be avoided by: determining a duration of time for maintaining the first distance between the display device and the first wearable device, wherein the target multimedia data is played if the duration of time is greater than a second threshold. Accordingly, in case the duration is less than the second threshold, the playing of the target multimedia data is refused.
In the above process, the first distance needs to be smaller than the first threshold, for example, the first threshold may be set to any one of 3 to 5 meters, if the first threshold is set to 5 meters, when the first distance is smaller than 5 meters, that is, when the first distance between the display device and the first wearable device is detected to be 0 to 5 meters by bluetooth, and when the duration is greater than the second threshold in the first distance range, the distance is considered to be stable, and when the above two conditions are met, the display device plays the target multimedia data, for example, the second threshold may be set to 5 seconds.
In step S604 of the device control method, determining target multimedia data corresponding to the first wearable device specifically includes the following steps: determining target multimedia data corresponding to the first wearable device from the historical play record; determining a playing stopping position of the target multimedia data; the method for playing the target multimedia data specifically comprises the following steps: and continuing to play the target multimedia data at the pause playing position. The pause position is a position where the playing of the target multimedia data is last completed in the playing progress of the target multimedia data, for example, the total playing time of the target multimedia data is 60 minutes, and if it is found in the history that the playing of the target multimedia data was last paused at 35 minutes and 30 seconds, the target multimedia data can be continuously played at 35 minutes and 30 seconds.
In the above process, the first wearable device may provide a child account number for logging in for the child, and according to the previous history play record of the first wearable device, the target multimedia data corresponding to the first wearable device worn by the child may be found, and when the child selects to continue to watch the target multimedia data that has not been watched last time, the pause play position of the target multimedia data is determined from the history play record, and the target multimedia data continues to be played.
In the above step, determining the target multimedia data corresponding to the first wearable device from the history play record specifically includes the following steps: determining a first multimedia set corresponding to a first wearable device from a historical play record; determining the remaining playing time of each multimedia data in the first multimedia set; and determining target multimedia data from the multimedia data with the residual playing time length larger than the third threshold value.
In the above step, the first multimedia set corresponding to the first wearable device worn by the child includes at least one multimedia data, and the remaining playing time of each multimedia in the first multimedia set is determined, if the first multimedia set includes two multimedia data, where the remaining playing time of one multimedia data is less than 1 minute, and the remaining playing time of the other multimedia data is greater than 10 minutes, the multimedia data with the remaining playing time greater than 10 minutes is determined as the target multimedia data; if the first multimedia set comprises three multimedia data, wherein the remaining playing time of one multimedia data is less than 1 minute, and the remaining playing time of the other two multimedia data is greater than 10 minutes, one of the two multimedia data with the remaining playing time greater than 10 minutes is selected to be determined as the target multimedia data.
Through the analysis, the multimedia data with the remaining playing time greater than the third threshold value is screened from the first multimedia set to obtain the target multimedia data. In an optional embodiment of the present application, the target multimedia data may also be determined by: that is, the remaining playing time is greater than the third threshold and not greater than the usable time of the first wearable device in the preset mode (e.g., the child mode). Therefore, the appropriate multimedia data can be determined more accurately, and meanwhile, due to the fact that the relation between the remaining playing time and the available time is considered, the problem of sudden interruption in the watching process can be avoided, and user experience is improved.
In the device control method, the control instruction is an instruction generated by the first wearable device when the played time of the target multimedia data is longer than a first preset time, and the first preset time is a set maximum time for single viewing or a remaining viewing time of the first wearable device.
Before the device control method shown in fig. 6 is executed, the display device establishes a connection relationship with the first wearable device, and the connection manner is not limited to the HiLink, the trust ring, or the like. If the remaining available watching time length of the children stored in the first wearable device is greater than 0 and the current time is not in the rest time period, after the mode of the children is entered, the display device displays the page when the children are watched, the watching interface is locked, and the children are not allowed to watch the multimedia data. Or if the current time is in the rest time period or the remaining viewable duration of the child stored in the first wearable device is less than or equal to 0, after entering the child mode, the display device immediately displays the page when the child is viewed, and locks the viewing interface, the child is not allowed to view the multimedia data, or the display device directly enters the screen locking interface.
Referring to fig. 9, fig. 9 is a schematic diagram of interaction between a child watch and a display device according to an embodiment of the present application. Step 901, after a child wears a child watch and approaches to a display device, the child watch detects that the child watch is worn by the child through a wearing detection function, the display device can judge a distance between the child and the display device by acquiring the distance between the child watch and the display device, the display device acquires a first distance between the child watch and the display device through a camera, when the first distance is detected to be smaller than a first threshold value, if the first threshold value can be set to any value in 3-5 meters, if the first threshold value is set to 5 meters, the display device sends a prompt message to the child watch when the first distance is smaller than 5 meters, the child is informed that the distance is appropriate, after receiving the prompt message, the child stops approaching a large screen and keeps time of about 5s at least, in this step, in order to prevent the child from being too close to the display device, the distance can be set to be 3-5 meters. Step 902, when the display device detects the above state and detects that there is no adult watch around (there is no adult watch around indicating that the parent is not nearby), the charging duration (i.e. the time when the child can watch the video) is obtained from the child watch through step 903, and meanwhile, the application of the child mode is started in step 904, and the child mode is entered. The display equipment continues playing the video which is loved by the child according to the history record of the video played by the child before, and simultaneously sends a message that the video starts to be played to the child watch by the large screen;
step 905, after receiving the message, the child watch starts a child timing application and starts to record time;
step 906, synchronizing the child watch and the large screen every other one minute, wherein the remaining time for the child to watch the video, namely the remaining watching time length, is to be noted that one minute is a settable value and can be specifically adjusted according to actual conditions;
step 906', the display device synchronizes the watched time length recorded this time to the child watch, and it should be noted that step 906' is an optional step, that is, the display device may not synchronize the watched time length recorded by the display device to the child watch, and certainly, in some scenes with strict requirements on data synchronization, step 906' may also be executed to negotiate the accuracy of the information recorded by both parties;
and 907, when the recording time reaches the recharging time length, the child watch side displays that the time balance is insufficient, timing is stopped, the child watch sends a notice message when the child watch watches the child watch to the large screen, the large screen stops playing the video after receiving the notice message sent by the child watch, and the child watch enters a rest state or a locking state to prevent the child from watching the video excessively.
The above is mainly a description of the slave display device side, and the following describes the embodiments of the present application in detail from the wearable device side.
Referring to fig. 10, a flowchart of another device control method provided in the embodiment of the present application is a method for describing a process of the device control method from the perspective of a wearable device, and as shown in fig. 10, the method specifically includes the following steps:
step S1002, the wearable device receives notification information from the display device, wherein the notification information carries a play start time of the target multimedia data;
step S1004, timing by the wearable device according to the playing starting time, and determining the played time length of the target multimedia data according to the timing time length;
step S1006, when the played time length is longer than the specified time length, sending a control instruction to the display device, wherein the control instruction is used for controlling the display device to enter a rest mode, and in the rest mode, stopping playing the target multimedia data continuously.
In steps S1002 to S1006, the wearable device corresponds to a child watch, when a first distance between the wearable device and the display device is smaller than a first threshold, if the first threshold is set to any value of 3 to 5 meters, if the first threshold is set to 5 meters, the wearable device waits for notification information sent by the display device when the first distance is smaller than 5 meters, and determines a play start time and a play duration of the target multimedia data according to the notification information, meanwhile, when the play duration of the target multimedia data acquired by the wearable device is greater than a specified duration, the wearable device sends a control instruction to the display device, and controls the display device to enter a rest mode, where the specified duration is a duration in which an adult (parent) logs in a mobile phone mobile terminal or a watch through a corresponding adult account to recharge the wearable device worn by the child, that is, the person may extend an allowable play duration of the target multimedia data through the portable device.
Before the wearable device receives the notification information, the display device may directly enter a child mode to continue playing the target multimedia data when detecting that the first distance is smaller than a first threshold; or the wearable device may send a trigger instruction to the display device to trigger the display device to play the target multimedia data, and then receive notification information sent by the display device, specifically: the method comprises the steps that the wearable device obtains a first distance between the wearable device and the display device; and under the condition that the first distance is smaller than a first threshold value, the wearable device sends a trigger instruction to the display device, wherein the trigger instruction is used for triggering the display device to enter a specified working mode, and in the specified working mode, the target multimedia data are continuously played.
As described above, in order to achieve the quick access of the child mode, the distance (first distance) between the wearable device and the display device may be used as the access condition, wherein the first distance may be determined by the following methods, but is not limited thereto: acquiring the signal intensity of the display device detected by the wearable device; determining a first distance corresponding to the signal strength; or, receiving a first distance determined by the display device, wherein the first distance is determined by the display device according to the detected signal strength of the wearable device.
In the above process, the signal strength of the display device detected by the wearable device or the signal strength of the wearable device detected by the display device is related to the distance between the wearable device and the display device, so that the distance between the wearable device and the display device can be determined by the signal strength, wherein the signal strength is proportional to the distance, the farther the distance is, the worse the signal strength is, and conversely, the closer the distance is, the stronger the signal strength is. In an alternative embodiment, a set of mappings between signal strength levels and distances may be maintained at the wearable device and/or the display device side, such that if a corresponding signal strength level is determined, a corresponding distance may be determined according to a mapping in the set of mappings.
In step S1004 of the device control method shown in fig. 10, when the played time length of the target multimedia data is determined according to the timing time length, for a scene with low accuracy requirement, the played time length in the notification information may be directly used as the final/actual played time length, and for a scene with high accuracy requirement (for example, a scene such as a game), the transmission time delay of the information needs to be considered. For the latter, this can be achieved by: the wearable device determines a first duration between the moment of starting playing and the moment of receiving the notification information; the wearable device starts timing from the moment when the notification information is received, and determines a second time length counted in the timing process; and determining the played time length of the target multimedia data according to the first time length and the second time length.
In the above step, if the wearable device receives that the play start time carried in the notification information sent by the display device does not coincide with the current time (i.e. the time when the notification information is received), first determining the time when the notification information is received, and then determining the play start time carried in the notification information, for example, when the current time is 8: 04, that is, the first duration is 4 minutes, according to step S1014, it can be considered that the wearable device starts to record the played duration of the target multimedia data from receiving the notification information, that is, the second duration, and as can be seen from the above analysis, the second duration includes 4 minutes of the first duration, and therefore, the played duration of the target multimedia data is the difference between the second duration and the first duration.
In another optional embodiment, if the play start time carried in the notification information received by the wearable device and sent by the display device is the current time (that is, the time when the notification information is received), the wearable device starts timing while receiving the notification information, and the display device plays the target multimedia data at the same time, in the process, the transfer time of the notification information between the wearable device and the display device is negligible, that is, the played time length of the target multimedia data recorded by the wearable device is considered to be consistent with the played time length of the target multimedia data played by the display device.
In step S1004 of the device control method shown in fig. 10, before the wearable device receives the notification information from the display device, the allowable viewing duration stored in the wearable device may be further adjusted, for example, the allowable viewing duration is increased or decreased, specifically: wearable equipment receives duration adjustment information sent by terminal equipment, wherein the duration adjustment information at least comprises: an adjustment amount and an adjustment type; and adjusting the specified time length according to the adjustment type and the adjustment amount so as to obtain the final allowable watching time length, wherein the adjustment type comprises the following steps: increasing the specified time period and decreasing the specified time period. It should be noted that, if the duration adjustment information sent by the terminal device is not received, the specified duration stored in the wearable device may be directly used as the final allowable viewing duration.
In the above step, the wearable device and the terminal device have a communication connection relationship, so that the duration adjustment information sent by the terminal device can be received, the terminal device can be a mobile terminal and other devices such as a mobile phone and a tablet computer lamp which log in an adult account, and parents can recharge the wearable device worn by children through the mobile terminal and other devices which log in the adult account, and the parents can set the time for the children to watch multimedia data through the mobile terminal and other devices to obtain the specified duration, and send the specified duration to the wearable device worn by the children.
In order to enable the display device to timely acquire the remaining playing duration of the target multimedia data, before sending the control instruction to the display device, the following steps may also be executed: synchronizing the played time of the target multimedia data to the display device according to a preset time period, so that the display device can know the played time in time to prepare for subsequent operations, for example, the display device can compare the played time with the actual played time according to local records, if the played time and the actual played time are consistent or the error is within a preset range, the played time counted by the wearable device is determined to be valid, otherwise, the played time is determined to be invalid, and the display device feeds the error back to the wearable device so that the wearable device can update the played time determined by the timing function in time.
In the above process, the preset time period is settable, for example, set to perform time synchronization every one minute.
In step S1002 in the device control method shown in fig. 10, before the first distance between the wearable device and the display device, the following steps may be further performed: and under the condition that the display device is detected in the detection range of the wearable device, the wearable device establishes connection with the display device, wherein the connection mode is not limited to a HiLink mode, a trust ring mode and the like. It should be noted that, the distance required for the wearable device to establish a connection with the display device is different from the first distance, for example, when the wearable device and the display device establish a connection by using the bluetooth communication module, since the communication distance of the bluetooth protocol is generally about 10 meters, and the distance suitable for viewing multimedia data is often less than 10 meters, the distance between the wearable device and the display device can establish a communication connection before being shortened to the first distance.
The device control method is described in detail above from the display device and the wearable device side, and for ease of understanding, the control process of the entire device is described below with reference to fig. 11, taking the wearable device as a child watch as an example.

And 1112, synchronizing messages once every y minutes, namely synchronizing the video watching time, of the display device and the child watch, calculating the video watching time of the child watch after the child watch receives the messages, and if the video watching time of the child exceeds the total watching time charged by the parents or the time needing rest is reached, sending a prompt message to the display device by the child watch, wherein the prompt message is used for informing the display device to lock.
In a scene that a watch and a display device interact when a parent is not nearby, step 1101, after the child watch and the display device are connected (the connection mode is not limited to bluetooth, hiLink, trust ring, and the like), it is to be noted that the watch worn by the child is the child watch, step 1102, the parent charges the child watch with a time length through a mobile terminal logged in by an adult account, step 1103, the child wears the child watch and is close to the display device, the child watch performs distance detection through bluetooth (or the display device performs distance detection through bluetooth), when it is detected that the first distance between the child watch and the display device is within 3m-5m and the time kept in the distance range lasts for 5s, step 1104, the display device detects whether the child watch exists within 3m-5m nearby (by querying device information and token corresponding to the watch in a device cloud platform, it is determined whether the watch is the adult watch), if it is detected that the child watch does not exist nearby, step 1109, it is detected that the current time is a time period or whether the remaining watch is greater than 0, if it is detected that the child watch is not displayed in a resting time period or a child watch is displayed in a video display mode when it is not displayed in the child watch, and the child watch is not displayed in a child watch display mode when it is displayed in the child watch mode; step 1111, when the child watch detects that the current time is not in the rest time period and the remaining time for watching the video is greater than 0, the display device automatically enters a child mode, so that the child can watch the video conveniently. And step 1112, synchronizing the messages once every y minutes, calculating the time that the child watches the video after the messages are received by the child watch side, and if the time that the child watches the video exceeds the total watching time charged by the parents or the time that the child needs to have a rest is reached, sending a prompt message to the display device by the child watch, wherein the prompt message is used for informing the display device to lock.
It is to be noted that, in both of the scenes shown in fig. 11, x and y are variables that can be set, and when there are a plurality of display devices, the display of the video being played is regarded as the viewing device.

Referring to fig. 15, a schematic diagram of switching multimedia data according to a distance by a display device according to an embodiment of the present application is shown in fig. 15, where the display device currently plays first multimedia data, the first multimedia data is multimedia data that a parent is watching, such as a movie, a tv show, and the like, and when a distance between a first wearable device worn by a child and the display device is a first distance, the first distance exceeds a connection range between the display device and the first wearable device, the first wearable device cannot establish a connection with the first wearable device, and at this time, the display device continues to play the first multimedia data for the parent to continue watching.
In fig. 15, when the child Tong Peidai is continuously close to the display device, and the distance between the first wearable device and the display device is a second distance, the second distance is within a connection range between the display device and the first wearable device, such as the connection range is 3-5 meters, and when the second distance is any one of the distances between 3-5 meters, the first wearable device establishes a connection with the display device, and since the first wearable device worn by the child is already connected with the display device at this time, the display device currently needs to stop playing the first multimedia data that the parent is watching and start playing the second multimedia data that the child wants to watch. In addition, since the child wears the first wearable device to be continuously close to the display device, the distance between the first wearable device and the display device is changed from the first distance to the second distance, and therefore, the second distance is smaller than the first distance.
In the system structure diagram shown in fig. 14, the system further includes a designated electronic device 1403, the designated electronic device is configured to receive authorization request information sent by the display device before the display device stops playing the first multimedia data and starts playing the second multimedia data, where the authorization request information is used to apply for the designated electronic device for the right to play the second multimedia data.
The authorization request information sent by the appointed electronic equipment receiving and displaying equipment is applicable to the following scenes: the display device detects that the designated electronic device exists in the connection range, and the current display device stops playing the first multimedia data watched by the parent and starts playing the second multimedia data watched by the child.
When there is a specific electronic device worn by an adult or a parent around the display device, the display device needs to send authorization request information to the specific electronic device to request to confirm whether the child can view the second multimedia data currently, the authorization request information may be displayed on the specific electronic device worn by the parent, and the parent makes response information to the authorization request information by selecting a corresponding button or clicking a corresponding option. Generally, the response information mainly includes two types: the first response information and the second response information.
In an alternative embodiment, the designated electronic device sends first response information of the authorization request information to the display device in response to a first operation of a target object (i.e., a user) for the authorization request information, where the first response information is used to notify the display device to stop playing the first multimedia data and start playing the second multimedia data.
The first operation described above may be a scenario as follows: the parents specify the electronic equipment through an adult watch, an adult bracelet and the like worn by the parents, click the option of 'consent' or select a button corresponding to 'consent'. The appointed electronic device sends first response information of authorization request information, namely information that parents approve children to watch second multimedia data, to the display device after receiving first operation executed by a user, and the display device stops playing the first multimedia data watched by the parents and starts playing the second multimedia data watched by the children after receiving the first response information.
In another optional embodiment, the designated electronic device sends second response information of the authorization request information to the display device in response to a second operation of the target object (i.e., the user) for the authorization request information, where the second response information is used to notify the display device to stop playing the first multimedia data, and after the display device stops playing the first multimedia data, the display device is turned off.
The second operation described above corresponds to the following scenario: the parents click the option of 'disagreement' or select a button corresponding to 'disagreement' through appointed electronic equipment such as an adult watch or an adult bracelet and the like worn by the parents. After receiving a second operation performed by the user, the designated electronic device sends second response information of the authorization request information to the display device, that is, information that the parent does not agree with the child to view the second multimedia data, and after receiving the second response information, the display device stops playing the first multimedia data that the parent is viewing, and closes the display device.
In a scenario corresponding to the second operation, since the first wearable device worn by the child has entered the connection range of the display device, the display device plays the first multimedia data watched by the parent at this time, but the parent does not agree with the child to watch the second multimedia data, the display device stops playing the first multimedia data watched by the parent after receiving the second response information, and closes the display device, wherein the operation of closing the display device may be controlled by the parent, or may be automatically closed by the display device, which is not limited here.
According to the system of the embodiment of the application, when the first wearable device is close to the display device, the display device can send the authorization request information to the appointed electronic device, and responds to the authorization request information according to the operation of the user on the appointed electronic device, so that the content played by the display device is controlled, the operation is simple, and the control is convenient.
In the system, the designated electronic device sends first response information of the authorization request information to the display device, the display device sends first notification information to the first wearable device after receiving the first response information, namely after the display device receives information that the designated electronic device authorizes the child to watch the second multimedia data, and the first notification information is used for notifying the first wearable device to start timing of the playing process of the second multimedia data.
After the first wearable device receives the first notification information, responding to the first notification information, recording a first time length for playing the second multimedia data, and notifying the display device to stop playing the second multimedia data when the first time length is greater than a first preset time length, wherein the first preset time length is a maximum single-watching time length set by a parent for the first wearable device worn by the child through a designated electronic device or a remaining watching time length of the first wearable device.
As for whether the first preset time length is the maximum time length or the remaining viewable time length, the first preset time length may be determined according to actual conditions. In an alternative embodiment, if the parent has just set the maximum duration of the single viewing for the first wearable device worn by the child, in this case, the first preset duration may be considered as the maximum duration of the single viewing, for example, if the parent has just set the maximum duration of the single viewing for the first wearable device to be 30 minutes, the first wearable device notifies the display device to stop playing the second multimedia data when the playing of the second multimedia data exceeds 30 minutes.
In another optional embodiment, if the parent sets the viewing duration for the first wearable device worn by the child, but the viewing duration remains, and the parent does not need to set the viewing duration again, the first preset duration may be considered as the remaining viewing duration of the first wearable device. For example, the viewing duration of the first wearable device set by the parent before is 30 minutes, the remaining viewing duration of the first wearable device is 20 minutes when the child has viewed the second multimedia data for 10 minutes through the first wearable device before, and when the child wears the first wearable device again to view the second multimedia data, the first wearable device notifies the display device to stop playing the second multimedia data when the second multimedia data is played for more than 20 minutes.
